Ferrari SF90 Stradale Ushers New Era for Italian Supercar Maker


Ferrari introduces a new chapter in its history with the introduction of the SF90 Stradale—the supercar maker’s first-ever series production plug-in hybrid electric vehicle. The carmaker says this new car is meant to represent a true paradigm shift—one that combines the performance of a V8 engine with not one, not two, but three electric motors. The result? 1,000 horsepower and a power-to-weight ratio of 1.57 kilograms per horsepower.

As the top-of-the-line model in Ferrari’s series line-up, the SF90 Stradale is named for the 90th anniversary of Scuderia Ferrari, underscoring the strong link that Ferrari’s racing cars has on its road cars.

On its own, the turbocharged V8 engine is already capable of delivering 780 horsepower, the highest output of any 8-cylinder in Ferrari’s history. The remaining 220 horsepower is delivered by three electric motors—two in front and one at the back. This makes the SF90 Stradale the first-ever Ferrari sportscar to be equipped with all-wheel drive. Mated to an 8-speed dual clutch automatic, 0-100 km/h comes in 2.5 seconds and 0-200 km/h in just 6.7 seconds. The impeccable grip is provided by the entirely electric front axle making possible torque vectoring.


The introduction of the hybrid architecture was a challenge to Ferrari engineers. However, they managed to keep the overall weight, rigidity, and center of gravity optimized thanks to the new of multi-material technology such as carbon fiber.

Designed internally at the Ferrari Styling Centre, the SF90 Stradale offers more compact overhangs and a frontward-cabin design. It features a curved windshield, slender A-pillars, and a wide track creating a well-proportioned, sleek car. The compact bubble-shaped cabin has an aeronautical feel further emphasized by the two body-colored rear flying buttresses.

In an absolute first for a Ferrari, the SF90 Stradale uses matrix LED headlight technology to improve visibility in all driving conditions thanks to active beam control.


The rear of the car is dominated by high exhaust pipes which are the result of optimization of the exhaust line layout. Because the powertrain is significantly lower in the car than in the past, the designers were also able to lower the car’s tail.

Inside, the interior debuts a new design direction for Ferrari which will be carried over into the brand’s entire future range.

The designers took a futuristic approach to the interface concept with a strong focus on creating a wraparound aeronautically-inspired cockpit with particular emphasis on instruments. In a first for the brand, the central instrument cluster comprises a single 16-inch digital HD screen which curves towards the driver to make it easier to read and to emphasize the F1-style wrap-around cockpit effect. This is the first time this type of screen has been adopted in a production car.


The “hands-on-the-wheel” approach continues here with the SF90 Stradale’s steering wheel integrating a variety of touch commands such as headlight control, windshield wipers, indicators, and driving mode control all without having to take the hands off the wheel. Of the new touch controls, the compact but functional pad on the right-hand spoke allows the driver to navigate the central cluster screens, while voice and cruise controls are on the left-hand spoke.

Even the key on the SF90 Stradale is new—with a full keyless technology, it will be introduced across the rest of the model range. In addition, thanks to a special compartment in the center tunnel, it becomes an integral part of the cabin.

Finally, for the first time on a Ferrari, clients can choose between the standard car and a version with a more sports-oriented specification. The Assetto Fiorano specification includes significant upgrades, including special GT racing-derived Multimatic shock absorbers, extra lightweight features made from high-performance materials such as carbon-fiber (door panels, underbody), and titanium (springs, entire exhaust line), resulting in a weight saving of 30 kilograms. Another difference is the high downforce carbon-fiber rear spoiler which generates 390 kg of downforce at 250 km/h. The Assetto Fiorano includes Michelin Pilot Sport Cup2 tires designed specifically to improve performance on the track in the dry. They feature a softer compound and fewer grooves than the tires provided as standard.
